This is a longshot, and my apologies in advance for my vagueness but...
The episode was a reading of a short story by some old-school highly acclaimed spec-fic author, recorded by permission of the author's estate. The story is 30+ years old.
The story takes place in a far future post apocalyptic distopia.
The main character is considering paying a high price for a relived memory slash alternate past experience from some wizardlike individual and his machine. He decides against it, and goes on with his happy life which is described in brief. In the end, it turns out that his happy life really was a alternate memory furnished by the wizardlike guy and his machine, and the lead character pays for the experience with all of his possessions, which consist of a spool of wire, (fill in other pieces of trivial scrap scrap here).
Ring any bells?
